I have set up a dashboard with multiple charts to display several aspects of a single dimension and have coloured each chart the same in order to easily distinguish members. I am having an issue, however, with the combo chart. When I set the colours and line type (solid, dash, or dot) everything works fine but when I save the dashboard and exit then open the dashboard again the colours have changed and the lines have reverted to solid lines. Is this a known bug in the chart type?
For clarification I am using 5 measures on my combo chart, four on the primary axis and one on the secondary axis.
